1dX lubrication spray?

(1/1)

Sycotek:
Brand new 70-200 II used on my 7D for a month or so (5000+ frames ) not a spec of dirt on the rear element.

70-200 II On the 1DX used for 2 events 3500 frames what looks like lubrication spray on the rear element.

Never had this issue with my old 1D's but none of them were this fast - anyone else have this issue?

I have had this spray on my 50mm but that's easy to clean in comparison.

May be is the same that got my sensor all dirty.....

Quite a few different things can result in little specs ending up on the rear element. Maybe even a little spittle if you were talking while changing lenses? Or as you suggest, oil from the new mechanism. Nothing to be concerned about, grab some isopropanol and a microfiber cloth, or better yet, some of those little packaged lens wipes. Problem solved.
